IntelliJ Idea Profiling

Giriş

Açıklaması şöyle

Sometimes, unfortunately, a breakpoint is not enough and you need to use some more serious tools. Mostly those are tools used to detect memory leaks and high CPU usage. The Profiler in IntelliJ provides a lot of the functionalities that previously we needed external tools for.

You can open the Profiler pane through the View Menu|Tool Windows|Profiler or it might already be visible somewhere in the left|bottom|right corners. If there is a Java process running it will appear there.

The interesting bits are hidden in the context menu.

This will show you a timeline graph of the memory and CPU usage of the app while it’s running.

It can be very useful if you want to gauge where the app is at in terms of resource usage or detect any abnormal spikes or drops in either of those.
